Kev Hloov Tsheb luv luv yog qhov ua txhaum hluav taws xob yog qhov cuam tshuam hluav taws xob uas yuav tshwm sim thaum tsim khoom, kev ua thiab kev thov ntawm ib qho twglub cavwinding. Thaum qhov kev sib tshooj luv-tig cov kab yuam kev luv luv tshwm sim, nws puas tuaj yeem kho tau thiab qhov ntsuas yuav tsum tau npaum li cas?
Cov winding thiab embedding ntawm lub cev muaj zog windings yuav muaj kev cuam tshuam tsis zoo ntawm cov xov hluav taws xob hauv hluav taws xob. Txawm hais tias nws yog enameled Electromagnetic hlau lossis Mica Hlau Wrapped Hlau Siv nyob rau hauv kev tsim cov windings, nws yog qhov nyuaj kom tsis txhob muaj teeb meem zoo li no. Cov txheej txheem moulding ntawm cov molding winding kuj muaj qhov cuam tshuam zoo rau qhov zoo ntawm hluav taws xob xaim xaim xaim xaim txheej txheej. When the mold is inappropriate and the winding shape design is unreasonable, it will lead to serious insulation damage problems during the molding process, which is a potential quality hazard for inter-turn short circuit problems.
When similar problems occur in the winding before dipping in paint, necessary insulation remedial measures can be taken to isolate and protect the damaged electromagnetic wires; Thaum lub tshuab cua rwb thaiv tsev kho mob, insulating xim tuaj yeem ua lub luag haujlwm ua tau lub luag haujlwm hauv kev txhim kho cov rwb thaiv tsev ntawm lem. It turns out that The insulation performance of the injured electromagnetic wire may fully meet the insulation performance requirements of the motor; however, if the insulation effect is not very obvious, it will inevitably lead to electrical quality failures during the operation of the motor, that is, inter-turn short circuit problems during operation.
In comparison, the inter-turn short circuit problem that occurs in the winding before the motor is running is mostly discovered through the inter-turn insulation tester, and there is still an opportunity to take some effective remedial measures; Thaum cov cua tshuab cua luv luv tshwm sim thaum lub tshuab kuaj tas los yog kev ua haujlwm ntawm lub cev muaj zog ua haujlwm nrog kev kho me me.
When an inter-turn short circuit fault occurs during the operation of the motor, the fault is manifested as a multi-turn insulation problem, and some even affect the entire coil. Muaj kev cuam tshuam loj dua yuav nyob rau theem-rau-theem rwb thaiv tsev thiab rwb thaiv tsev av. Qhov ntawd yog, qhov kev sib cais sib txuas tsis tau muaj qhov cuam tshuam loj dua, thiab kev ua txhaum kev cuam tshuam loj yuav ua rau muaj kev txhaum loj dua. Lub rwb thaiv tsev txheej ntawm lub electromagetic hlau yog yuav luag hauv cov duab hauv lub xeev, yog li tag nrho cov cua yuav tsum tau hloov.
